Temperature and humidity sensor, similar to the popular DHT11 or DHT 22, with digital I2C interface in the through-hole case. The system can be controlled using a microcontroller or any commissioning set , for example, Arduino. Before using, you need to see the documentation.
- Supply voltage: 3.3 V to 5.5 V
- Average current consumption: 0,35 mA
- Measurement range: -40 °C to +80 °C
- Resolution: 16 bits (0.1 °C)
- Accuracy: 0.5 °C
- Response time: 2 s
- Measuring range: 0% to 99.9 % RH
- Resolution: 16 bits (0.1% RH*)
- Accuracy ±3 RH* (at 25 °C)
- Measuring range: 2 sec
*RH - relative humidity is expressed in percents. It is the ratio of actual moisture in the air to the maximum number that the air can keep at a given temperature.
The product is compatible with Arduino
Online, available is library for Arduino with a description of the connections which simplifies the maintenance of the sensor.
Example of connection with microcontroller
The diagram shows the method of connection of the system with any microcontroller using the single-wire interface.
VDD - supply voltage, SDA and SCL - data and a clock line with pulling-up resistors of 10 k Ohm, GND - the ground of the system.
